Our dominant business class is best fitted to the impulsive style, but I should qualify this.
There was a time when the dominant businessmen were much more far-sighted. They planned their approach. They built their businesses and products to last. They were still pretty damned ruthless, but they at least had a rational interest and were aware of the need to preserve the economic structures they operated in, and the greater society those structures grew out of.
Now it is well-understood that today's industrialists have become shackled to finance. It isn't only finance that has become dominant, but that the industrial structures themselves have become financialized. This results in an economic milieu where the impulsive and short-sighted thrive. The objective is to accumulate power and wealth as quickly as possible, which is apparent in the behaviors of the most powerful businessmen, the most powerful politicians, as well as the characteristics of mass-produced goods, services, and cultural artifacts, economic policy in general, and foreign policy in general. Corporate assets that haven't yet been outsourced are cannibalized to generate returns. Employees are shed. Old ideas are recycled again and again.
But just because you're impulsive doesn't mean you survive easier in this society. Beyond a given personality gaining ascendancy in a society, closed, fraternal/familial networks are able to capture more and more gains in power, so that plenty of people of all personality styles are left out in the cold, though if you have that impulsive business personality, you're more likely to rise a little higher than your struggling peers. There is a reason that a majority of the most powerful people in the world are white males, though that balance is set to change as well.
Of course, the various personalities are represented in the power structure governing this society, but the personalities most close in frequency to that of the business class - as well as a certain ethnic tribe - are usually the closest to power. To visualize this, think of a plane that contains the spectrum of personalities, and there is a mountain of runaway power towering out of the business/impulsive personality. Or don't! Different modes of thought work for different people.
The most powerful people in the world are functionally sociopaths: they traffic in power and influence, but they don't actually represent anything of lasting substance. They are empty vessels which take on the surrounding personality of the powerful community they are part of. Impulsivity is a perfect trait for this environment. You produce a bright shiny object and get everyone's attention, and then when time passes, and there is opportunity for scrutiny, you pull away and move on to something else before anyone realizes what is going on.
In this environment, a group think arises, with activity centered around the most insistent, urgent, and somewhat talented individuals eagerly pursuing their own narrow aims.
It is important to stress that it isn't impulsivity or business that is absolutely evil; they both have their place in human ecosystems. It is the vast asymmetry in power that they currently enjoy. It is the imbalance.
